This matchup is a grind against a deck full of colorless lands and artifacts/colorless Eldrazi, so Obsidian Charmaw is excellent both as a cheap flier and for blowing up Eldrazi Temple or Ugin's Labyrinth. Nihil Spellbomb answers Shifting Woodland by turning off its delirium and denies graveyard value, such as the cards Malevolent Rumble puts into their graveyard and the cost reduction Emrakul gets from card types there. Molten Collapse is a clean answer to their big Eldrazi threats, including Emrakul, which only has protection from instants. Lightning Bolt is weak since it rarely kills their big Eldrazi threats, and Street Wraith's swampwalk does nothing against a deck with no Swamps. Keep Thoughtseize and Flare of Malice in as your best proactive disruption against their top-end bombs like Emrakul.
